Module: Wireless Communication Systems (41009)


This module deals with the theoretical basis and most relevant wireless communication systems and discusses their architecture, interfaces and services. In the theoretical part the cellular concept, radio propagation and diversity, digital modulation, coding and scheduling as well as multiple access schemes are explained to derive the basic system concepts of deployed systems. The corresponding radio interfaces are explained and compared. As an example of today’s broadband mobile systems based on IP technology, LTE and 5G are presented in detail. System planning and maintenance issues are introduced as well. A special highlight consists of the economic importance and costs of the different components of the system. In an outlook future research directions towards beyond 5G / 6G systems as well as means for collaborative research are presented. It is the objective of this module to link communication theory with industrial research and development towards deployed systems in our societies and economies.
